Note: When the Auto Sash control is being retro-fitted, fix the bracket to allow for over-travel
of the sash.

Sash position sensor
The sash position sensor is fitted with a mounting bracket which can be fitted in four different
orientations to enable the sensor draw wire to be correctly aligned.
1.
Offer up the sensor to determine the best fixing position on the fume hood framework.
Where possible, ensure the sensor draw wire runs straight out of the sensor housing, in line
with the cable housing extension. Where the wire runs at an angle to the sensor, ensure the
angle is as small as possible to prevent the wire from rubbing on any part of the sensor body,
including the cable housing extension.

Mark the fixing holes on the framework and attach the sensor.
